SPECIFICATION forming part of Letters Patent No. 702,145, dated June 10,1902.

Application filed February 4, 1902. Serial No. 92,582. (No model.)

To all whom it may concern: I V

Be it known that 1, JOHN H; MoRRfsoN, a citizen of the United States,residing at Kingsbridge, in the county of New York and State of NewYork,have invented certain new and useful Improvements in Skate Clamps, ofwhich the following is a full and complete specification, such as willenable those skilled in the art to which it appertains to make and usethe same.

The object of this invention is to provide an improved clamp for holdingskates in the operation of grinding or sharpening the same and with thisand other objects in viewthe invention consists in a device of the classspecified constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, ofwhich the accompa nying drawings form a part, in which the separateparts of my improvement are designated by the same reference charactersin each of the views, and in which- I I Figure 1 is an end view ofmyimproved skate-holder and showing the method of using the same, and Fig.2 a plan view of the construction shown in Fig. l. v In the practice ofmyinvention Iprovide a clamp for the purpose specified, which comprisesa bottom portion or base a, with which I are connected two verticalscrews 17, each of which is provided with two clamp -nuts 0, which arein the form of ordinary thumb-n utsf The screws 17 are connected withthe base por tion a at or near the opposite ends thereof in" any desiredmanner, and mounted on these screws between the clamp -nuts 0 are two Iclamping-bars e, the central parts of which are preferably curvedbackwardly, and in practice the runner f of the skate g is passedbetween the clamping-bars e and securely clamped in position by means'ofthe nuts 0." I have also shown in the drawings a table It, provided withsupports 2', in which is mounted a shaft j, having an emery or otherwheel is, and the object of providing two nuts-on each of the screws 17and mounting the clamping-bars a between the same is to provide meansfor vertically adj ustin'g' the clamp or the bars thereof, betweenwhichthe runner of the skate is passed, so that the said run- I per willbe in direct line with the center of thejstone it when the runner isheld in proper position, as shown in Fig. 1, and by this means I providefor grinding the bottom surface of the runner smoothly and evenly andavoid the grinding thereof at the opposite edges.

- The table 71. and stone is are only shown for the purpose ofindicating the operation of the device and the object of making theclamp in the manner described, and any suitable support may besubstituted for said table. .It will be understood, of course, that theclamp is moved back and forth across the table, so as to grind theentire bottom portion of the runner of a skate, and my invention is notlimited to the table or support, as it is .possible to operate thedevice without any other support than thesupport of the stone.

Having thus fully described my invention, what I claim as new, anddesiretose'cure by Letters Patent, is-

1. A device of the class described comprising a base,vertical screwsnear the opposite ends thereof, each of which is provided with twoset-nuts and two clamping-bars mounted on said screws between said nuts,substan @memb'ers connected therewith, two verticallyinovableclamping-bars mounted on said end members, and two nuts mounted-on eachof said end members above and below said bars, whereby the verticalposition of said bars Witnesses:
